Pre-charged to 25psi, it offers triple the drawdown capacity of traditional galvanized tanks in a compact, weather-resistant design—saving energy, reducing pump wear, and ensuring pure, odorless water for years. ## Description Product Description The WaterWorker pre-charged tanks utilize a butyl composite diaphragm, which flexes up and down based on water level and air pressure, as the pump fills the tank with water the air above the diaphragm is compressed, increasing the pressure in the tank until the pump cut-off pressure is reached. When water is drawn from the tank, the pressure inside the tank decreases until the pressure switch starts the pump. The amount of usable water for every pump cycles is called drawdown. The greater drawn-down capacity you select, the less your pump cycles saving energy, money, and extending your pump life. Advantages over galvanized well tanks: Pre-charged tanks do not have water-logging problems like the galvanized tanks. The air and water are totally separated using a diaphragm. No external air controls needed. Pre-charged tanks have a much larger draw-down for the same physical size. Larger draw down reduces pump cycles and pump wear, i.e. at 30/50 PSIG range three times the draw-down for pre-charged tanks of the same physical size. Pre-charged Tanks completely empty during each pump cycle. Pre-charged Tanks are much smaller and easier to handle that galvanized well tanks. Pre-charged tanks with a 30/50 Pressure Switch would be one-third the size of a galvanized tank with the same drawdown. Deep Well Jet Pumps could use either a vertical tank or a horizontal tank, depending on space requirements and sizing. Submersible Pump applications would usually use vertical tanks, again based on proper sizing. Shallow Well Jet Pumps could use vertical or horizontal tanks, based on proper sizing. The rule of thumb in sizing is to count the number of fixtures in the home, i.e. sinks, showers, toilets, dishwasher, faucets, washing machines, outside faucets, etc. and multiply it by 3. Example: a house with 11 fixtures x 3 would be 33-Gallon tank. We would suggest our 44-Gallon tank, which is the next larger sized tank.This is a Hazmat non-returnable item From the Manufacturer The WaterWorker pre-charged tanks utilize a butyl composite diaphragm, which flexes up and down based on water level and air pressure, as the pump fills the tank with water the air above the diaphragm is compressed, increasing the pressure in the tank until the pump cut-off pressure is reached.

Good quality tank and works fantastic. Should last another 30 years. Review: On time delivery - Arrived on time - we got a 3 day window for delivery and it came on first day, so that was great.
